Transmitters with these parts were kits, and had the mod to make them legal to be built without an FCC license by anybody. Once these parts are removed and jumpered, the output power jumps way up past the license free 100 milliwatts limit, and increase the range significantly. I forgot to mention this before.

Many thanks to Bob, Bob, and Bob for this information. (all the good guys seem to be named Bob!)

I did a post on this before, but replaced the 100 ohm with a 56 ohm, which was a adequate power increase. Bob G sent me a schematic set for all the Controlaire GGs, and it then became apparent that the resistor is not used in the earlier, and non-kit factory built versions. RCBOB then told me why this was done, it was so it could be legally sold as a kit and comply with the FCC regulations.

Jay,

Thanks for this. I will take a look tonight when I get home from work. My TX does have a kit feel about it.

Hello Jay,

Unfortunately my transmitter does not have the 100 ohm resistor and .01 cap. Mind you there does appear to be an output tuning coil. Looking at the board it does not look like a kit, although it has been fiddled with. For example, it looks like the crystal has been replaced at some time in the past. I can take a picture of the board if it will help.

Peter
